1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract

purpose of the studyThis study aimed to estimate the proportion of intraoperative blood loss absorbed by gauze during major spine surgeries and identify factors influencing blood loss. PATIENTS AND

methodsA prospective cohort study of 28 patients undergoing elective major spine surgery with blood loss exceeding 1 L was conducted. Blood loss was estimated using the gravimetric method for gauze and measurement of suction canister contents. Demographic and surgical data were collected.

resultsOn average, 21.19% of total blood loss was absorbed by surgical gauze. When considering blood loss in the suction canister, an additional 28.33% was absorbed by gauze. Two-column surgeries and longer surgical durations were associated with significantly higher total blood loss and suction-collected blood. No statistically significant differences were observed in the percentage of blood loss absorbed by gauze across most demographic and clinical factors.

conclusionThis study provides insights into intraoperative blood loss distribution during major spine surgeries. Surgeons and anesthesiologists should add approximately 28% to the blood loss measured in the suction canister for a more accurate assessment. The findings can guide clinicians in anticipating blood loss and improving transfusion management, potentially leading to better patient outcomes.
